Armenian and Azerbaijan’s presidents Serzh Sargsyan and lham Aliyev

YEREVAN, October 26. /TASS/. International mediators try to coordinate the date for a meeting between Armenian President Serzh Sargsyan and his Azerbaijan’s counterpart Ilham Aliyev on the Nagorno-Karabakh settlement.

The preparation for the meeting of Armenian and Azerbaijani leaders is one of the key issues on the agenda of the mediators’ regional visit, OSCE Minsk Group US Co-Chair James Warlick said.

The Minsk Group spearheads the OSCE's efforts to find a peaceful solution to the conflict in Nagorno-Karabakh, a disputed region between Armenia and Azerbaijan. The group is co-chaired by France, Russia, and the United States.

Warlick and other co-chairs of the Minsk Group from Russia and France, Igor Popov and Pierre Andrie, respectively, will hold talks with the Armenian president and Foreign Minister Eduard Nalbandyan on Monday.

The goal is to discuss the principles of the agreement on the comprehensive settlement of the conflict and to try to reach progress on creating the atmosphere of confidence between the sides.

"We expect the meeting to be held in late 2015," the US diplomat said. The meeting could take place after the referendum on constitutional reform due in Armenia on December 6.

Both presidents agree to step up dialogue, he said. "We are willing to use this visit to clarify the dates of the meeting."

On Tuesday, the co-chairs will go to Nagorno-Karabakh, and then will travel to Azerbaijan’s capital Baku, the diplomat said.
